BMW 3 Series (2019) Review

BMW 3 Series (2019) At A Glance

+More spacious than before. Upgraded engines. Very refined.

-Saloons not as practical as SUVs in many people's eyes.

On average it achieves 77% of the official MPG figure

The BMW 3 Series is wider, longer and lighter than its predecessor - with BMW insisting that it will remain at the top of its class in terms of handling. Still clearly a 3 Series, the latest model features a larger kidney grille and headlights similar to the bigger 5 Series. 

A longer wheelbase translates to a roomier cabin. BMW is promising an extra 11mm of rear legroom and more headroom for those in the front and back. Larger doors should make getting in and out of the new 3 Series easier, while the rear seats can accommodate three child seats. With the rear seats left up, boot space is 480 litres, while the rear seats can be dropped 40:20:40 to increase luggage capacity.

There's more kit as standard, with the entry-level model featuring an 8.8-inch central touchscreen infotainment system, increasing to a 10.3-inch system on the M Sport model. Apple CarPlay is standard across the range, although drivers will have to pay for a subscription service after the first year.

Like the Mercedes-Benz 'Hey Mercedes' personal assistant that made its passenger car debut in the A-Class, drivers and passengers in the new 3 Series will be able to access functions and retrieve information by saying 'Hey BMW'.

Described as 'the ideal co-driver', the personal assistant will learn your routines and habits allowing it to answer questions and even provide casual conversation ('Hey BMW, what is the meaning of life?' is an example provided by BMW).

The 3 Series comes with a digital key as per bigger models in the range, allowing it to be locked and unlocked from a smartphone.

From launch, buyers can choose from a range of four-cylinder engines in the 320d diesel and 330i petrol. The diesel produces 190PS with peak torque of 400Nm, taking it to 62mph in 7.1 seconds (automatic: 6.8 seconds), while the four-wheel-drive xDrive version takes 6.9 seconds.

If I have a puncture in a runflat tyre, do all four need replaced?
"I check my tyre pressures each week and have discovered a very slow puncture on one of my BMW 320i front tyres. They are BMW-approved run flats. I know run flats are not meant to be repaired and I understand why. If this tyre has never been driven 'flat' (max 3 PSI under inflated), does that still hold true? Also, do I need to replace all four or just the front two?"
None of the leading tyre retailers will repair a run flat tyre following a puncture. Most manufacturers advise against repairing run flat tyres. If the deflated tyre has been driven on, it could have compromised its strength, and it is impossible for a fitter to know if the tyre was driven on for longer/faster than recommended after a puncture. You'll be hard press to find any outfit that would repair. As for replacing four tyres or just two, it depends on how worn they are. The BMW Xdrive system can't cope with more than 2mm in tread depth between front and rear.

I can't drive my car with the warning light on but the dealer won't look at it. What do I do?
"Six weeks ago, my six-month-old BMW G20 3 Series had an engine management light come on. I called my dealer and booked it in (10 days was first appointment). I asked if it was okay to run with this light on for 10 days and they asked me to call BMW emergency services to get a technician to look at it. The technician told me I couldn't run it and he would arrange for my car to be looked at immediately. It was to be taken to the dealer and a hire car would be provided and I should be at the dealer at 4pm that day. Another agent then called me to confirm and arrange the Hire Car. Got to the dealer and of course they knew nothing about it, no hire car and a 70 miles round trip wasted. I called BMW Emergency and there reply was " there's nothing in the notes so nothing I can do". I raised a complaint with BMW and got a letter 2 days later saying they were looking into it. Its now 6 weeks and I've heard nothing, I escalated to BMW and their stance is that its not their problem as BMW Emergency service is with Allianz not them. My stance is that my warranty (of which BMW emergency service is part) is with BMW and if they choose to subcontract it, that's their issue not mine. What's your advice on this one?"
The line of responsibility here stops with the dealer that sold you the car. Tell them in writing that you want the car fixed or replaced. If they are unable to do either of these things. you will need to seek legal advice to reject the car and get a refund (minus a fair deduction for the usage you have already had fro the vehicle) . For legal help, start with Citizens Advice (it's free). For your consumer rights, see:

Which SUV is the best for road handling?
"I want to buy a medium size SUV, can you tell me which model is best for handling? "
Probably the BMW X3 or Mazda CX-5. Consider an estate car like a BMW 3 Series if handling's important.

I want to buy an EV or PHEV but I worry about changing from manual to auto - what do you think?
"When electric vehicles are discussed, one thing I do not see mentioned is whether older drivers should change from manual to electric. Electric vehicles must be automatic or equivalent to an automatic. My journeys are totally suitable for an electric vehicle or Plug-In Hybrid; 90% short trips. With home charging, the new BMW 330e with its 40-mile range on electric would be ideal (if somewhat extravagant). I would rarely have to visit a garage but I do want a vehicle that would do 250 miles before needing a charge. However, I passed my driving test in 1962 and my other half tells me not to touch automatics. My daughter’s car was hit by a car driven by an elderly driver that accidentally went 30-foot across a car park from a parking space and my neighbour, driving an automatic, wrote off five cars in a car park in a similar fashion. I am quite happy on the outside lane of the motorway in my Porsche Boxster (manual) and I don’t think going to an electric vehicle would be a problem after a couple of hundred miles of practice but I am a bit wary of making the change. What are your views on this?"
I'm a big fan of automatics - they're easier and more relaxing to drive and make a lot of sense unless you particularly enjoy changing gears. A plug-in hybrid sounds like it'd suit your needs very well, assuming you can charge it at home. But there are more affordable PHEVs on the market than the 330e - consider a Volkswagen Passat PHEV or Hyundai Ioniq PHEV.
